The storage of person.
Preferably, measuring cup uses corrosion resistant aluminum material.
By using above-mentioned technical proposal, nitric acid liquid is known from experience and aluminium material reacts, be passivated the material on measuring cup surface,
Form fine and close protective layer, with prevent measuring cup further corroded by nitric acid lead to not using.
Preferably, standard test weight uses corrosion resistant Teflon material.
By using above-mentioned technical proposal, standard test weight not will receive the corrosion of nitric acid in use and weight occur
Variation in amount and volume, it is ensured that the accuracy of testing result.
Preferably, the total length of counterweight suspension hook and standard test weight be slightly less than weight brackets to measuring cup bottom it is vertical away from
From.
By using above-mentioned technical proposal, standard test weight will not contact after being completely immersed in nitric acid liquid with measuring cup bottom
And the effect of power occurs, it is ensured that the accuracy of testing result.
Preferably, one end of counterweight suspension hook with bolt is adjusted, adjusts bolt and is inserted in the semi-ring of counterweight suspension hook upper end two
On the connector to extend out.
By using above-mentioned technical proposal, after counterweight suspension hook is connected weight brackets, suspension hook can be reduced by adjusting bolt
Internal diameter, it is stably buckled on weight brackets.
Inside diameter surface as preferred counterweight suspension hook one end is equipped with washer, and washer two sides is smooth and is pasted onto inside meter on one side
Face, thickness are about 2mm.
It by using above-mentioned technical proposal, is not susceptible to slide after counterweight suspension hook connects weight brackets, and can be further
Guarantee the stability of connection.
In conclusion the utility model has the following beneficial effects:
The included measuring cup and standard test weight of detector are placed in the groove of the flapper of apparatus subject side, are convenient for
It carries and uses；Flapper is opened when use and takes out measuring cup, standard test weight and counterweight suspension hook, and measuring cup is placed on above detector
Pallet in, nitric acid liquid to be measured is added thereto, because measuring cup be aluminum material, after contact and reacts with nitric acid liquid give birth to
At one layer of fine and close protective layer, so that measuring cup will not be further corroded and influence to use；Standard test weight is hung by counterweight again
Hook is connected with the weight brackets on measurement pedestal, and one end of suspension hook can reduce its internal diameter by adjusting bolt, adds
The effect of inside diameter surface washer is firmly secured at standard test weight and counterweight suspension hook on weight brackets, and because of standard weight
The total length of code and counterweight suspension hook is less than the vertical range of bracket and measuring cup bottom, so standard test weight will not connect with measuring cup bottom
Triggering raw active force influences the accuracy of testing result, and the Teflon material of standard test weight makes it will not be by when contacting nitric acid
Corrosion；Standard test weight is completely immersed in after liquid because of the buoyancy by nitric acid liquid, is measured the detecting element below pedestal and is surveyed
The difference of the fixed value of the actual pressure value and standard test weight that obtain is exactly the buoyancy size that standard test weight is subject in nitric acid liquid, inspection
Instrument inside scale unit is surveyed further according to Archimedes' principle: m=ρ (liquid) V (row) g calculates the density, concentration and wave of nitric acid to be measured
U.S. degree；Measuring cup, standard test weight and counterweight suspension hook are put into the groove of detector side and are closed flapper after the completion of detection,
Play the role of storage.

Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
Embodiment: a kind of anhydrous detector for nitric acid, the side of detector main body 1 is provided with flapper 8, measuring cup
11 and standard test weight 4 and counterweight suspension hook 6 be placed on it is easy to carry and use in the groove 12 of flapper 8；It is beaten when use
It opens flapper 8 and takes out measuring cup 11, standard test weight 4 and counterweight suspension hook 6, measuring cup 11 is placed on the table of 1 top tray 2 of detector main body
Face, nitric acid liquid to be detected are put into measuring cup 11, and because measuring cup 11 is aluminum material, one layer is generated after reacting with nitric acid solution
Fine and close oxide layer, can protect measuring cup 11 and is not corroded；The bolt 10 of 6 upper end of counterweight suspension hook is unscrewed, weight brackets 5 is allowed to block
In the inside diameter surface of counterweight suspension hook 6, then bolt 10 is tightened again, so that counterweight suspension hook 6 is fixed on together with standard test weight 4
On weight brackets 5, because the inside diameter surface of counterweight suspension hook 6 has one layer of rubber pad 9, so that the connection of counterweight suspension hook 6 and weight brackets 5
It is more stable, secured, and because the total length of standard test weight 4 and counterweight suspension hook 6 is less than weight brackets 5 to the vertical of 11 bottom of measuring cup
Distance would not also influence the accuracy of final detection result so standard test weight 4 will not generate active force with measuring cup 11；
Standard test weight 4 is totally immersed in the nitric acid liquid in measuring cup 11 again, so that it will not by nitric acid solution for Teflon material
Corrosion and change itself weight and volume；Standard test weight 4 in nitric acid liquid by buoyancy so that being connected to measurement
The numerical value that the detecting element of pedestal 3 measures is less than the fixed value of standard test weight 4, and the difference of the two is the size of buoyancy, internal
Scale unit is further according to Archimedes' principle: density, concentration and the Baume degrees of m=ρ (liquid) V (row) g calculating nitric acid；Detection is completed
Measuring cup 11, standard test weight 4 and counterweight suspension hook 6 are put into the groove 12 of detector side and are closed flapper 8 afterwards, plays receipts
The effect received.
